structured concurrency

• use of java 21 running of conncurrency in a structured/procedural way, instead of using completable future (callback)

• Makes following the code easier to read

• Observable, the stack trace points to correct location of failure

• exception handling is more intuitive

• Error handling short circuiting

  • if one fails then other sub tasks will fail if need all tasks to complete
